Embodiment 1

[0041] The fruit of Cornus officinalis is dried and crushed, 150 kg is taken and 500 L of 85% ethanol aqueous solution is extracted at room temperature for 3 hours, and the filtrate (1) and filter residue (1) are obtained by filtration; the filtrate (1) is concentrated to 20 L under vacuum or reduced pressure at 55° C. Filtrate (2) and filter residue (2) were obtained by membrane filtration once; add 60L water to the filter residue (1), then adjust the pH to 4 with 0.1mol / L hydrochloric acid, then add acid protease and peptidase to a final concentration of 80U / L , carry out enzymatic hydrolysis at room temperature for 3 to 5 hours to obtain an enzymatic hydrolysis solution. Add 1000L of 95% ethanol to the enzymolysis solution and extract at room temperature for 2h, filter to obtain the filtrate (3) and filter residue (3); the filtrate (3) is concentrated to 20L under vacuum or reduced pressure at 55°C, and filtered once with a ceramic membrane to obtain the filtrate ( 4) and f...

Embodiment 2

[0044] The fruit of Cornus officinalis is dried and crushed, 300kg is taken and added with 500L of 85% ethanol aqueous solution for extraction at room temperature for 2 hours, and the filtrate (1) and filter residue (1) are filtered to obtain the filtrate (1); Filtrate (2) and filter residue (2) were obtained by membrane filtration once; add 120L water to the filter residue (1), then adjust the pH to 4 with 0.1mol / L hydrochloric acid, then add acid protease and peptidase to a final concentration of 100U / L , carry out enzymatic hydrolysis at room temperature for 3 to 5 hours to obtain an enzymatic hydrolysis solution. Add 2000L of 95% ethanol to the enzymolysis solution and extract at room temperature for 3 hours, filter to obtain the filtrate (3) and filter residue (3); the filtrate (3) is concentrated to 30L under vacuum or reduced pressure at 55°C, and filtered once with a ceramic membrane to obtain the filtrate ( 4) and filter residue (4); After the filtrate (2) and the fil...

Abstract

The invention relates to a method for comprehensive utilization of Cornus officinalis, comprising the following steps: drying and crushing the fruit of Cornus officinalis, extracting with alcohol, filtering, adding acid protease and peptidase to enzymatic hydrolysis at room temperature, extracting with alcohol again, filtering, and combining the filtrates Apply to ADS‑2 macroporous resin column for adsorption, and obtain pure morroniside after elution; put the filter residue on a silica gel column, crystallize and recrystallize once to obtain pure ursolic acid and loganin.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of natural products, and relates to a method for comprehensive utilization of dogwood. Background technique [0002] The ripe and dry fruit of Cornus officinalis, after removing the pit, is the precious medicinal material potato meat. The pulp contains 16 kinds of amino acids, in addition, it contains a lot of elements necessary for the human body. In addition, it contains saponin raw sugars, polysaccharides, malic acid, tartaric acid, phenols, resins, tannins and vitamins A and C with strong physiological activity. The pulp is used as medicine, which is astringent blood tonic and tonic; it can invigorate the stomach, nourish the liver and kidney, and treat anemia, low back pain, nervous and heart weakness and other diseases. Its nature and flavor are sour and astringent, enter the liver and kidney channels. Sour and astringent, it has the effect of nourishing the liver and ki...
